Error message

Invalid configuration

Error code

x102

Description

One of Dr.Web for Linux components cannot operate because of incorrect configuration settings.

Resolving the error:

1.If you do not know which component causes the error, try to determine it by reviewing the log file.

2.If the error is cause by the SpIDer Guard component, the mode selected for the component operation is probably not supported by OS. Check the selected mode and change it, if necessary. You can do it by setting the value AUTO (the Mode parameter in the [LinuxSpider] section of the configuration file).

To view and correct the mode, you can use the commands of the command-line management tool.

•To set the value to AUTO, execute the command

# drweb-ctl cfset LinuxSpider.Mode AUTO

•To restore the parameter value to the default, execute the command

# drweb-ctl cfset LinuxSpider.Mode -r

If the error persists, build and install the loadable kernel module for SpIDer Guard manually

Note that operation of SpIDer Guard and of the loadable kernel module is guaranteed only on the supported UNIX distributions (see System Requirements and Compatibility).

3.If this error is reported by SpIDer Gate, there is probably a conflict with another firewall. For example, it is known that SpIDer Gate conflicts with FirewallD in Fedora, CentOS, Red Hat Enterprise Linux (on every launch, FirewallD corrupts traffic routing rules indicated by SpIDer Gate). To resolve this error, restart the Dr.Web for Linux by executing the command

# service drweb-configd restart

# drweb-ctl reload

Note that if you allow FirewallD to operate, the noted SpIDer Gate error can repeatedly occur on every restart of FirewallD, including a restart of an OS. You can resolve this error by disabling FirewallD (refer to the manual of FirewallD included in the manual of your OS).

4.If the error is reported by another component, restore the component settings to the defaults by any of the following methods:

•Use the drweb-ctl cfshow and drweb-ctl cfset commands.

•Edit the configuration file manually by deleting all parameters from the component section.

5.If the previous steps did not help, restore Dr.Web for Linux settings to the defaults.

To do this, clear the contents of the file /etc/opt/drweb.com/drweb.ini (it is recommended to back up the configuration file), for example, by executing the following commands:

# cp /etc/opt/drweb.com/drweb.ini /etc/opt/drweb.com/drweb.ini.save
# echo "" > /etc/opt/drweb.com/drweb.ini

Restart Dr.Web for Linux after clearing the contents of the configuration file by executing the command

# service drweb-configd restart

If the error persists, contact technical support and be ready to name the error code.

Error message

Incompatible software detected

Error code

x109

Description

A Dr.Web for Linux component cannot be in operation because an incompatible software is detected. This software interrupts correct component operation.

Resolving the error:

1.If this error is reported by SpIDer Gate, most likely that there is an incompatible software in operating system. This software generates rules for the NetFilter system firewall, which prevents SpIDer Gate from correct operation. Probably, you have Shorewall or SuseFirewall2 installed in the system (in SUSE Linux OS). The application that configure the NetFilter system firewall sometimes check the integrity of the specified rule system and rewrite it. This is the main reason of SpIDer Gate conflict with such applications.

Reconfigure incompatible software so as it does not interfere in SpIDer Gate operation. If it is not possible, disable the software so as it does not load at the operating system startup any more. You can try to configure the SuseFirewall2 application (in SUSE Linux OS), following the steps:

1)Open the configuration file of SuseFirewall2 (by default, this is the /etc/sysconfig/SuSEfirewall2 file).

2)Find the following text block:

# Type: yesno
#
# Install NOTRACK target for interface lo in the raw table. Doing so
# speeds up packet processing on the loopback interface. This breaks
# certain firewall setups that need to e.g. redirect outgoing
# packets via custom rules on the local machine.
#
# Defaults to "yes" if not set
#
FW_LO_NOTRACK=""

3)Set the parameter value to “no”:

FW_LO_NOTRACK="no"

4)Restart SuseFirewall2 by executing the following command:

# rcSuSEfirewall2 restart

Note that if SuseFirewall2 does not have the FW_LO_NOTRACK option in its settings, to resolve the conflict, disable the application so that it does not load at the system startups any more (for example, it is necessary for OS SUSE Linux Enterprise Server 11).

5)After reconfiguring or disabling the conflict application, restart SpIDer Gate (disable it and enable again on the relevant page).

2.If the error is reported by another component, disable or reconfigure the incompatible software so as to prevent any interference with the Dr.Web for Linux operation.

If the error persists, contact technical support and be ready to name the error code.

# drweb-ctl cfset LinuxSpider.Mode AUTO
# drweb-ctl reload

4.If operating system you are using does not support fanotify or this mode does not allow SpIDer Guard usage for full control of a file system and LKM mode usage is obligatory, do not use the Xen hypervisor.

If the error persists, contact technical support.

Symptoms: Main window of Dr.Web for Linux is disabled, status indicator in notification area of desktop displays an critical error mark, and drop-down menu contains only one disabled item Loading.

Description: Dr.Web for Linux cannot start because core component drweb-configd is not available.

Resolving the error

1.Uninstall Dr.Web for Linux by entering the following command:

# service drweb-configd restart

2.If this command returns error message, or has no any effect, install drweb-configd component (package) separately.

Also note that this may mean, that PAM authentication is not used in the system. If so, please install and configure it.

3.If the previous actions do not help, uninstall Dr.Web for Linux and then install it again on the system.

For details on how to install and uninstall Dr.Web for Linux or its components, refer to sections Installing Dr.Web for Linux and Uninstalling Dr.Web for Linux.

If the error persists, contact technical support.

Symptoms

1.The status indicator is not displayed in the notification area after the user logged in.

2.When trying to execute the command:

$ drweb-gui

opens the Dr.Web for Linux main window.

Description: The problem could mean that necessary additional library libappindicator1 is not installed in your system.

Resolving the error

1.Make sure that the package libappindicator1 is installed in your system by the following command:

# dpkg -l | grep libappindicator1

2.If the command does not output any result to screen, you should install the package, using any available system package manager. After that, log out and then log in again (log in).

Also note that this may mean, that PAM authentication is not used in the system. If so, please install and configure it.

3.If the previous actions do not help, uninstall Dr.Web for Linux and then install it again on the system.

For details on how to install and uninstall Dr.Web for Linux or its components, refer to sections Installing Dr.Web for Linux and Uninstalling Dr.Web for Linux.

If the error persists, contact technical support.

Symptoms

1.After disabling SpIDer Gate, all network connections are broken (outgoing and, may be, incoming via SSH and FTP protocols) and cannot be re-established.

2.Search through the NetFilter (iptables) rules using the following command:

# iptables-save | grep "comment --comment --comment"

returns non-empty result.

Description: This error is related to the incorrect NetFilter (iptables) operation, which version is earlier than 1.4.15. Because of this internal error, when SpIDer Gate adds the rules with a unique label (comment) to the list of rules, the rules are added incorrectly. As a result, on shutting down, SpIDer Gate cannot delete its rules of diverting connections.

Resolving the error

1.Enable the SpIDer Gate monitor again.

2.If you need SpIDer Gate disabled, remove the incorrect rules of NetFilter (iptables) by the following command:

# iptables-save | grep -v "comment --comment --comment" | iptables-restore

Note that the iptables-save and iptables-restore commands require the root privileges. To elevate your privileges, you can use the su and sudo commands. Note also that this command removes all rules with the incorrect comments, for example, added by other applications that also perform routing traffic.

Additional information

•To prevent this problem, it is recommended to upgrade your OS (or, at least, only NetFilter to version 1.4.15 or later one).

•You can also switch the diversion of connections towards SpIDer Gate into the Manual mode in the Dr.Web Firewall settings if you want to manually divert connections towards SpIDer Gate by specifying the required rules with the help of the iptables utility (this way is not recommended).

•For details, refer to documentation man: drweb-firewall(1), drweb-gated(1), iptables(8).

If the error persists, contact technical support.

Symptoms: Double click on an icon of a file or a directory runs the scanning in Dr.Web for Linux.

Description: The GUI has associated automatically files of a certaing type or directories with Open With Dr.Web for Linux action.

Resolving the error

1.Cancel the association between files of one type and Dr.Web for Linux. The associations are registered in the file mimeapps.list or in defaults.list. Files with local settings which were changed in a user profile are stored in the directory ~/.local/share/applications/ or ~/.config/ (these directories are usually appended with the attribute “hidden”).

2.Open the file mimeapps.list or defaults.list with any text editor (note that to edit the files, root privileges are required. If necessary, use the command su or sudo).

3.In the file, find the section [Default Applications] and association strings that look as <MIME-type>=drweb-gui.desktop. For example,

[Default Applications]
inode/directory=drweb-gui.desktop
text/plain=drweb-gui.desktop;gedit.desktop

4.If the right part (of the equality) of the association string contains links to other applications except drweb-gui.desktop, remove only the following link from the line: drweb-gui (drweb-gui.desktop). If the association contains link only to the application drweb-gui, remove the whole association line.

5.Save the changed file.

Additional information

•To check the current associations, use the utilities xdg-mime, xdg-open, and xdg-settings (included in the package xdg-utils).

•To read more about the xdg utilities, refer to the documentation man: xdg-mime(1), xdg-open(1), xdg-settings(1).
